There has been ongoing issue from Hex to Trivalent chrome conversion.
Just a few questions since I forgot the basics for coating.
Does Dacro coating always a hexavelent chrome?
What are the methods for hex to trivalenet chrome free -
Does geomet is an alternative for Hex to Trivalenet...
(1) For the given cumulated dimension, I need to have symbol 1 to be filled circle instead of crossed circle.
I don't see any option to change the current symbol.
( I tried to loook into Tools ----options but didn't help)
(2) For the manufacturer's mark - how to write in a dual text format...
Under the cumulated dimension, I don't see zero parallel to other dimension. I checked under the
properties____Symbol but somehow it doesn't allow to edit
Basically, I see the circle marked with 'x' mark but offset from otehr dimension. But,wanted to have zero parallel with other
dimension...
Looks like i'm facing difficulties since started using v5 after some time.
I'm using A0 Size sheet size for dwg & due to extensive detail dwg, I crossed the limit of sheet size.
One way, I can see to reduce the size of view that I don't want to do so any other suggestion?
I have 3d model & working on associated detail dwg.
As you know, when we draw the view from 3d models than need to delete a lot of extra lines to avoid misunderstanding.
Also, I deleted section line hatch mark.
Now, Even there is no change to model, sometimes i receive update command while...
I have solid part name called "X.CATpart" & associated "X.CATdwg" with many diemensions included.
For the same solid part "X", I received modified soild geometry with different part name.
Now, I just want to incorporate only changes to dwg & thats why I tried to save the new modified part...
Under Catia V5 drafting, I want to create dimension (arrow at one end only for larger dimension in detail view) but couldn’t find the proper command. It was easy with Catia V4 but not able to find option with Catia V5. Tried to use techoloical feature dimension but couldn't get/understand it...
I was just comparing air flow pressure drop for intake system - analytical results (start CFD- by out side vendor) vs actual testing
For the same flow - Analytical results showing more pressure drop (say 7 kPa) while actual testing shows around 3 kPa?
Does it mean Analytical Flow calculation...
I have few pdf dwg from originally Auto CAD & when i tried to print it - the quality of print is very bad. blurr print. Can anyone knows the solution?
Instant reply will be appreiciated.
It may be the easy question but can someone explain how to use command "view from 3D" under Catia v5 drafting mode?
Its been a long time since I used V5 so step by step will be helpful.
Can anyone share experience for GT power & Ricardo wave in terms of Intake & exhaust developement?
If need to go for training than any preference/suggestion for GT power vs Ricardo wave?
As the pistion accelerates downward and air will drawn to cylinder will cause a presseure depression behind the valve.The pressure depression travels away from the valve at the speed of sound and reflected at the open end with 180 degree phase difference. Pressure pulse will arrive back around...
Is any suggestion for SAE paper/literature on
(a) optimize volumetric efficiency using clean side of duct of air induction system (THanks Grelocock & someptingGuy for response in past)
(b) effect of noise from dirty side of duct of air intake system
The resonant frequency of helmoltz resonator, f = c/2*3.14 (A/VL)^.5 Where A is surface area & V is the cavity volme & L is the effective length.
My question is does it make a difference for Transmission loss/tuning of the system if use circular, or any other cross section like square with...
I would like to get internal solid volume (not the external) using catia v5. I alreday checked if thickness was created using subtraction of solid but that was not the case. And also has a lot of internal feature so difficult to sew surfaces.
I am using measure command but difficult to get the...
I used catia v5 GSD & extracted the surface of solid by eliminating extra feature. Now, i'm trying to thicken the surface using part design but getting error message:
" local degenration on surface body can't be built"
Is there any othe approach can apply?
I have two differnt duct connected through seal at one end. I used spline & sweep operation to create the duct but at the contact plane both are out of phase(where the seal mounted). Also, tried to give assembly constrain but didn't able to apply.
Is there any specific way to make sure the...
Does noise pass by having direct relation with 1st, 2nd...order or type of vehicle like 4/6 cylinder ?
or just a standard requirement like US has around 75 dBA. (While vehicle testing, the exterior noise shouldn't exceed 75 dBA or depends on counry requirement)
I have few 3D dumb solid Models of duct & would like to get center curve for each duct? I can create 3d Curve on the surface but can't able to get the centre curve which has been used to sweep/rib operation? (using cad system catia v5 R 16) I will appreciate if someone can reply with command list
I have one of the supplier supplying plastic duct having bellows for flexibility purpose & running Durability testing to check the flexing of duct. But, it did fail/brake before meet the requirement.(one of the convolute get teared) Did try different material like soft nylon, different bellows...
